Product Description
SC(B) serie products are resin cast dry type transformers that are installed indoor with fire prevention functions. They are the first choice for places with limited spaces, close to the load center, or special place which has higher requirements of fire-proof.
SC(B) series transformers are widely used in various industries and applications because of their safety, reliability, and environmental benefits. Such as power station, hospitals, factories, buildings, commercial centers, airports, transportation tunnels, chemical plants, ships,etc.
They can operate in harsh conditions such as high humidity, fire risk, and seismic events without compromising their performance or posing any hazard to people or property.
Key Advantages
- Low noise & low loss: advanced design and high quality grain oriented cold-rolled silicon steel
- Low partial discharge: ensure transformer long-running safely
- Strong capability resist to short-circuit: epoxy glass fiber mesh structure insulation & vacuum resin casting
- Good impacting resistance: high level insulation and fire prevention
